Synthesis and Characterization of a New Methacrylate Polymer with Side Chain Benzofurane and Cyclobutane Ring: Thermal Properties and Antimicrobial Activity
The synthesis of a new methacrylate monomer
(Benzofuran-2-yl)(3-mesityl-3-methylcyclobutyl)-
O-methacrylketoxime is described. The monomer was polymerized in 1,4 dioxane
solution at 65 °C using azobisisobutyronitrile as an initiator. The monomer and its
polymers were characterized by infrared, and 1H-NMR spectroscopy. The
glass transition temperature of the polymer was investigated by differential scanning
calorimetry and the apparent thermal decomposition activation energies
(Ed) were calculated by the Ozawa method using a Shimadzu thermogravimetric
analysis thermobalance. The Ed were values were determined to be 231 kJ mol-1. The
antibacterial and antifungal effects of the momomer and its homopolymer were also
investigated on various bacteria and fungi.
